Abstract
Introduction Dark colored gingiva is an esthetic concern that cannot be ignored, especially when accompanied by a high lip line or gummy smile. Gingival depigmentation is a periodontal plastic surgical procedure wherein the hyperpigmentation is removed or reduced by various techniques. Protecting the wound from mechanical trauma and stability of the surgical site during the healing process are among the most important advantages of periodontal dressing application after surgery. Aim This study is aimed to comparatively evaluate the effectiveness of reactive oxygen gel species (BlueM gel) and the traditional Coe-Pack dressing on gingival healing and pain after surgical depigmentation. Protocol This split-mouth randomized clinical trial will be conducted on 20 patients aged 18–45 years with maxillary physiologic gingival pigmentation classes (II) (III) and (IV) according to the Dummett–Gupta Oral Pigmentation Index (40 treated sites). The maxilla will be randomly divided into two symmetrical parts—from the right second premolar to the midline and from the midline to the left second premolar—to receive either BlueM gel or Coe- Pack as a dressing after surgical depigmentation with a scalpel. Various indices will be assessed, such as plaque index, papillary bleeding index, pain index, healing index and reepithelization index with toluidine blue, and the follow-up period will be one month. Expected results- A total of 20 patients will be included in this study. Statistically significant differences are expected to show in the pain index and healing index after one, two, three, four, and five days. The BlueM gel group is expected to show a higher significant difference after one, two, three and four weeks in the reepithelization index.
